i hope your wrong, because they did have 3 versions to make, and weren't gonna budge on that release date("no matter what"). fixing game breaking bugs( or trying to ) after the game is released isnt something new to beth. and its obvious that 360 gets more attention then the ps3 due to microsofts handouts for timed exclusive dlc and advertisemant. 360>PC>PS3
the game was rushed to get that release date, and nothing was going to get in there way... theyr fully aware of the issue, and i hope they were getting this patch ready in a hope to get it out before the issue blew up the way it has..
PS3, when it came to multiplatform games, was most of the times left in the dark, hiding behind Microsofts back.
I also hope I'm wrong. But I abandoned hope in Bethesda after leaving the issue in their game back from 3 years ago.
In my opinion, they rushed the port. If they rushed the whole game then we would see this bug on all platform's but because it happens only on PS3 makes me believe that they didn't take in account that the PS3's architecture is different from Xbox's and few changes in controls and game save directory would do fine without proper optimizing. Which of course didn't.
But if the above is true, then that means, since Fallout 3 they knew about this problem and didn't bother to fix it as they would still get their money, through the hype generated. Making them the biggest leeches of the gaming industry.
